1. What are the end products of photosynthesis?

Firlakuza [10]

Answer:

1. Glucose And Oxygen.

2. Transpiration is the process by which water is lost in the form of water vapour by evaporation from the surface of leaves and other serial parts of plant .

3. A. Cooling Effect : The water keeps on evaporating from the leaf surface during transpiration . The heat required for evaporation of water is obtained from the plant itself and thus, the plant cools itself when it is hot outside.

B. Transpiration Pull : As water evaporates from the leaf surface, the roots pull up more water from the soil to make up for the water loss during transpiration .As a result, important mineral salts are also brought along with the water. These salts are necessary for the growth of the plant .

4. Leaf Tendrils : Sweet Pea

Spines : Cactus

Scale Leaves : Onion

5. Pitcher Plant, Venus FlyTrap, Blodderwort

6. Normally plants propogate with the help of seeds contained in the fruits . But some new plants may also be produced from other part of the plant such as the roots, stems, and leaves . This type of reproduction is called vegetative propogation .

Kipish [7]

Out of the following given choices;

a. Valine instead of glutamic acid in the sixth position

b. Glutamic acid replacing valine in the first position

c. Extensive amino acid substitutions

d. Trinucleotide repeats

e. Frameshift substitutions

The answer is A. this is caused by a mutation in the beta thalassemia genes on one of the 46 human chromosomes (chromosome #11) of the individual. The alpha subunit is normal in people with sickle cell disease. When sickle hemoglobin releases oxygen in the peripheral tissues, the molecules tend to stick together and form long chains or polymers. These rigid polymers distort the cell and cause it to bend out of shape from the normative disc shape.
